yeah, you should be able to just drop and recreate postgres. As the
postgres superuser, something like:
dropdb postgres
createdb -T template1 postgres
OR if it fails not finding the postgres db, then
psql template1 -U postgres
create database postgres with template template1
As for the encoding, make a new db with the same encoding as your last
db, and try again. If that doesn't work, look up iconv in the
archives / google. Lets you convert from encoding to another.
The vacuumdb error is much more worrisome and makes me wonder about
your hardware / OS reliability / possible driver error.
